Windows 11 search is lagging after a recent Dropbox update

I'm dealing with a very frustrating problem on all 3 of my Windows 11 machines and I suspect a recent Dropbox update may be the culprit. When I press the Start button and search for a particular file or folder, the result shows up in "best match" but it's not fully loaded. Instead, the preview/details pane to the right just sits as a blank gray box for 5-10 seconds before the gray box finally populates. Only that point can I click on the "open file location" button and get to the right place in file explorer. Similarly, if I immediately click on the particular file/folder in "Best Match," there's a 5-10 second lag between when I click on the file/folder and when the file/folder opens up or goes to the right place in file explorer.  It's making all of my computers almost unusable for productivity tasks.
